Remove offset workaround in restoreGeom()

Way back in Qt4, there was an issue where (some?) windows would open
at a different location to where they were previously open. I've tested
the primary windows in Qt 5.14 on macOS, and the issue no longer seems
to exist, so this code is no longer useful.

The qtmajor > 5 check was a mistake introduced in 98a161cec624bbb7e58f57c869741b349d96cc9f;
it was intended to limit the code to Qt 5.

A quick grep of an add-on snapshot indicates there are no add-ons that
were using the offset param, so it has been removed.
